Propeller anode magnesium alloy is used for cathodic protection to prevent corrosion in marine environments. It sacrificially corrodes to safeguard metal components like propellers and hulls. This method is cost-effective and essential for extending the lifespan of underwater metal structures.
Size: Typically 7.5 kg to 23 kg (varies by application)
Grade: AZ63, AZ31, or similar high-purity magnesium alloys
Viscosity: Not applicable (solid material)
Buoyancy: Negative (sinks in water due to high density)
Material: Magnesium alloy with aluminum (3-6%) and zinc (0.5-3%)
Corrosion Protection: Sacrificial anode, protects submerged metals via galvanic action
Operating Temperature: -40°C to 60°C (standard range)
Electrochemical Potential: -1.6V to -1.7V vs. Ag/AgCl reference
Current Capacity: ~1100-1300 Ah/kg (theoretical)
Shape: Streamlined or trapezoidal for propeller shafts
Mounting: Bolt-on or welded straps (depends on design)
